Sorry, we are members like yourself and have no access to your account to see any breakdown of fees or the cost of postage labels you may have purchased from eBay .
This will give you a breakdown of your transactions, fees paid, money received.
https://www.ebay.co.uk/sh/fin/transactions
If the above still doesn't clear up the amounts, contact eBay Customer Services, they do have that access, and can explain any transaction and fee paid for you.
This is the easiest and quickest way to contact eBay Customer Services, for a Call Back option.

Lines open 8 a.m. - 10 p.m. on weekdays
9 a.m. - 6 p.m. on weekends.
Automated agents will be available on chat outside of the above hours.
I recommend contacting CS first thing in the morning as there's more chance of Dublin answering.
